1.3 Scope

1.4 Denitions

- Split: the heat pump is composed of two parts (an
outdoor unit to be located outdoors and a Hydraulic
module to be installed inside the home).

- Air/water: the outdoor air is the energy source .
This energy is transmitted to the heating water by the

heat pump.

- Inverter: the fan and compressor speeds are modulated

to suit the heat requirements. This technology
economises energy and permits operation with single
phase power supply, regardless of the power rating
of the heat pump, by avoiding high current demands
when started.

- COP (coefcient of performance: this is the ratio
between the energy transferred to the heating circuit
and the electrical energy consumed.

- hybrid: the Hydraulic module operates with dual energy
(air/water heat pump and integrated oil boiler).

- low NOx: Burner designed to minimise the emission
of Nitrogen oxides NOx in the fumes. Generally low

This heat pump permits:

- heating in winter,

- the production of sanitary hot water,

- controlling two heating circuits *,

NOx burners are considered to be burners whose
emission rate is below the most severe regulations at
that time. This limit chnages regularly according to the
regulations and technical progress.

- heating the pool*.

*: These options require the use of additional kits
(see § "optional equipment").

1.7 Operating principle

The heat pump transmits the energy in the outdoor air
to the home to be heated.

The heat pump is formed of four main elements inside
which a refrigerating uid circulates (R410A).

- In the the evaporator (item. 13, gure 8, page 9):
The calories are taken from the outdoor air and
transmitted to the refrigerating uid. As its boiling point
is low, it changes from the liquid state to the vapour
state, even when the weather is cold.

- --In the compressor (item 10 or 16, gure 8, page 9):
The vaporised refrigerating uid is pressurised and
thus carries more calories.

- In the condensor (item 1, gure 9): The energy in the
refrigerant is transmitted to the heating circuit. The
refrigerating uid returns to its liquid state.

- In the pressure regulator (item 9 or 15, gure 8, page 9):
The liqueed refrigerating uid is taken to low pressure
and returns to its initial temperature and pressure.

The heat pump has a regulator that controls the indoor
temperature based on the measurement of the outdoor
temperature, regulation by water logic. The ambient
sensor (optional) provides a corrective action to the
water logic.

The Hydraulic module is tted with a burner that has an
AON operation, on demand from the regulator:

- to provide additional heating during the colder
periods,

- to provide support for the domestic (DHW) or

- to take over on "Peak Tariff" days (load shedding
function or EJP, see page 30).

Priority is given to the operation of the heat pump.
When the heat pump is not sufcient for the heating, the
burner automatically takes over.

• Regulation functions

- The initial temperature of the heating circuit is
controlled by water logic.

- In function of an initial heating temperature, the power
of the outdoor unit is modulated via the "inverter"
compressor.

- Management of the supplementary heating.

- The daily timer programme allows comfort or reduced

ambient temperature periods.

- Switching between summer/winter operation is
automatic.

- Domestic hot water: Timer heating programme,
management of operation of the DHW circulation
pump.

- Ambient sensor*: The ambient sensor provides a

corrective action to the water logic.

- Management of a 2nd heating circuit*.

- Management of the heating of the swimming pool*.

*When the PAC (heat pump) is tted with associated options and kits

• Protection functions

- Anti-legionella cycle for the domestic hot water.

- A pressure switch monitors the hydraulic pressure.

If the pressure is below 0.5 bar, an error message is
displayed (369) and the heat pump is stopped.

(line 1610 at 65 °C) and reduced temperature
(line 1612 àat40 °C).

The default DHW programme (line 560, 561, 562, 563
and 564) is set for a comfort temperature from 0h00

to 5h00 and from 15h00 to 18h00 and a reduced

temperature for the rest of the day.
The reduced temperature value may be useful to avoid

restarting the DHW too many times and for too long

through the day.

The production of domestic hot water (DHW) is started
when the temperature in the tank is 7°C below (setting
of line 5024) the reference value temperature.

The domestic hot water (DHW) is produced by the
heat pump then completed if required by the burner. To
ensure there is an DHW value higher than 45°C, the
burner must be operated.

Depending on the setting of the parameter (1620), the
comfort temperature may be reached either

- 24 h / day,

- in line with the timer programme of the heating
circuit,

- in line with the DHW timer programme,

- during the off peak periods,

- during off-peak periods and depending on the

SHW time programme.

The production of SHW has priority over heating, but the
production of SHW is managed by cycles that regulate
the time spent heating and the production of SHW when
simultaneous demands occur.

A function for switching from "reduced" to "comfort"
is available on the front panel of the user interface
(see item 1, gure 43, page 36).

2.3 Unpacking and reserves

2.3.1 Receipt

When the courier is present, carefully check the general
appearance of the appliances, check that the outdoor
unit has not been in horizontal position.

In the event of disagreement, write to the courier within
48 hours mentioning all reserves and send a copy of
this letter to the After Sales Department.

2.3.2 Handling

The outdoor unit must not be in horizontal position
during transport.

Transport in horizontal position creates a risk of damage
to the inner tubes and the compressor suspensions.

Damage caused by transport transport in horizontal
position is not covered by the warranty.

2.3.4 Containment of refrigerant circuits

All refrigerant circuits fear contamination from dust and
moisture. If such pollutants introduced into refrigeration
circuit, they can contribute to degrade the reliability of

the heat pump.

" It’s necessary to ensure correct containment

connections and refrigerant circuits (hydraulic
unit, outdoor unit).

" In case of subsequent failure and expertise, the

nding of the presence of moisture or foreign

objects into the compressor oil would lead to
systematic exclusion of warranty.

- Check upon receipt that the ttings and the refrigeration
circuit caps mounted on hydraulic unit and outdoor unit
are properly seated and locked (impossible to loosen
bare hands). If this’s not the case, tighten them using
an against wrench.

- Check also that the refrigerant connections are
sealed (plastic caps or tubes crushed at the ends
and soldered). If the caps must be removed during
installation (tubes cut by example), put back them as
soon as possible.

2.4 Positioning

The choice of the position is particularly important
as having to move it later is a delicate operation that
requires a qualied person.

Choose the position of the outdoor unit and the hydraulic
module after discussion with the client.

Respect the max. and min. distances between the
Hydraulic module and the outdoor unit (gure 21, page

20), the performances and life of the system depend

on this.

2.5 Installation the outdoor unit

2.5.1 Installation precautions

" The outdoor unit must only be installed

outdoors. If a shelter is requried, it must have

large openings on all 4 sides and respect the

installation clearances (gure 14).

• Prefer a sunny position sheltered from strong and
cold dominant winds (mistral, tramontane, etc...).

• the appliance must be fully accessible for the
installation and later maintenance work (gure 14).

• Ensure that the connections can be made easily with

the hydraulic module.

• The outdoor unit can be exposed to the weather,
however avoid installing it in places where it will
become dirty or have excessive water dripping onto it
(under a leaky drainpipe for example).

• When operating water may escape from the outdoor
unit. Do not install the appliance on a terrace,
prefer a drained spot (bed of gravel or sand).
If the installation is in an area where the temperature
can be lower than 0°C for a long period, check that the
presence of ice does not present any danger. It is also
possible to connect a drain pipe to the outdoor unit
(see gure 15, page 16).

• No obstacles must block the air circulation through the
evaporator and from the fan.

• Keep the outdoor unit away from sources of heat or
inammable products.

• Ensure that the appliance does not disturb neighbours
or users (sound levels, draughts caused, low
temperature of the air blown out with the risk of freezing
plants in its path).

• The surface on which the outdoor unit is tted must:

- be permeable (earth, gravel bed...),

- be easily capable of supporting its weight,

- allow solid attachment,

- not transmit any vibrations to the home (anti-vibration

pins are available among the accessories).

• The wall bracket can not be used in conditions likely to
transmit vibrations, ground position is preferred.

2.5.2 Fitting the outdoor unit

The outdoor unit must be raised by at least 50 mm
from the ground. In snowy regions, this height must be
increased but must not exceed 1.5 m.

- Attach the outdoor unit using screw and spring or split
washers to ensure they do not come loose.

2.5.3 Connecting the condensates drain

If an evacuation pipe must be used:

- Use the elbow provided (C) and connect a exible
hose diameter 16 mm to drain off the condensates.

- Use the Plug(s) provided (B) to block the condensate
tray orice.

Fit so that gravity ow of the condensates is ensured
(waste water, rainwater, gravel bed).

" If it is installed in a region where the temperature

can drop below 0 °C for long periods, t a

tracing resistor to the drain pipe to avoid it
freezing up. The resistance trace must heat not
just the evacuation pipe but also the bottom of
the condensate drip tray of the appliance.

* In regions where there is often snow,

(H) must be higher than the average thickness of snow.

To facilitate the servicing operations and permit access
to the various parts, it is recommended that sufcient
space be left all around the hydraulic module.

" The warranty on the heater will not cover any

installation of the appliance in a chlorine rich

atmosphere (hairdressers, launderette, etc.) or

any other corrosive vapours.

This equipment may not be installed in a bathroom or a
shower room.

Be careful of the presence of inammable gas close
to the heat pump when it is installed, especially when
brazing is required. The appliances are not antiexplosion
and must therefore not be installed in an explosive
atmosphere.

- To avoid any condensation inside the condensor only
remove the refrigerating circuit plugs when making

refrigerating connections.

- If the refrigerant connection only occurs at the end of

the installation, be sure that the refrigerant circuit caps*
remain in place and tight throughout the installation

duration.

* (Hydraulic module side and outdoor unit side)

- After the work is carried out each time on the
refrigerating circuit, and before nal connection, ret
the Plugs to avoid any pollution of the refrigerating
circuit (sealing with adhesive is not allowed).

2.6.4 Connection pipe

The evacuation pipe must comply with the regulations

in force.

The cross section of the connection pipe must not be
smaller than the outlet nozzle of the appliance.

The connection pipe must be removable.
It is strongly recommended to t a ue regulator to the

pipe when the low pressure of the chimney is greater
than 30 Pa. The ue gas case is reversible (2 screws)
and the smoke outlet axis may be offset with respect to
the axis of the boiler to the right or to the left.

The evacuation nozzle is to be connected to the pipe so
that there are no leaks.

" This appliance uses the refrigerating uid

R410A.

Respect the legislation for handling refrigerating uids.

2.7.1 Rules and precautions

• After each operation on the refrigerating circuit, and
before the nal connection, ensure that the plugs are
tted so as to avoid any pollution of the refrigerating

circuit.

• Minimum tooling required

- Set of pressure gauges (Manifold) with exible hoses
for HFC (Hydrouorocarbons).

- Vacuum gauge with isolation valves.

- Special vacuum pump for HFC (use of a classic

vacuum pump only allowed if tted with a non return
valve for the suction).

- Disengageable aring tool, tube cutter, deburrer,
wrenches,

- Approved refrigerating uid detector (sensitivity 5g/
an).

" Tooling that has been in contact with HCFC (R22

for example) or CFC may not be used.

• The manufacturer refuses all responsibility for

warranty if the above values are not respected.

• Tube expanders (ared connectors)

" Lubrication with mineral oil

(for R12, R22) is prohibited.

- Only lubricate with polyolester refrigerating oil (POE).
If POE oil is not available, t without oil.

• Brazing on the refrigerating circuit
(if required)

- Silver brazing (40% minimum recommended).

- Brazing with a dry Nitrogen stream only.

• To eliminate the swarf from the pipes, use dryNitrogen to
avoid introducing humidity that can harm the operation
of the appliance. In general, take every precaution to
avoid humidity penetrating into the appliance.

• Thermally insulate the gas and liquid pipe to avoid
all condensation. Use insulating sleeves that resist
temperatures of over 90°C. In addition, if the level
of humidity where the refrigerating pipes risks
exceeding 70%, protect them with insulating sleeves.
Use a 15 mm thicker sleeve if the humidity reaches
80%, and a 20 mm thicker sleeve if the humidity
exceeds 80%. If the recommended thicknesses are
not respected in the conditions described above,
condensation will form on the surface of the insulation.
Finally, ensure that insulating sleeves are used that
have a thermal conductivity equal to 0.045 W/mK or
lower when the temperature is equal to 20°C. The
insulation must be impermeable to resist the steam
passing during the defrosting cycles (glass wool is
prohibited).

- 18 -

Cover the ared surface

with POE refrigerating oil.

Do not use mineral oil.

Installation and operating manual "1605 - EN"

alfea hybrid duo heat pump oil low NOx CH

2.7.2 Refrigerating connections

The connection between the outdoor unit and the
Hydraulic module must only be made with new copper
connectors (refrigerating quality) and individually
insulated.

Respect the diameters of the pipes and the authorised
lengths(gure 21, page 20).

If the refrigeration connections are exposed to
weathering or UV- and the insulation is not strong, it is
necessary to provide protection.

Handle the pipes and pass them through the walls with
the protection plugs in place.

If the distance between the outdoor unit and the
hydraulic unit exceeds the length of the maximum
conduits indicated in the table, an additional charge of
R410A must be loaded.

The quantity of R410A added must be suited to the
length of the refrigerating circuit so as to maintain the
performances of the heat pump and not damage the
compressor (gure 21, page 20).

2.7.3 Flaring

- Cut the tube with a tube cutter to the required length
without deforming it.

- Carefully deburr while holding the tube downwards to
avoid introducing swarf into the tube.

- Remove the are nut from the connector on the valve
to be connected and t the tube into the nut.

- Flare it leaving the tube protruding fro the expandable
aring tool.

- After aring, check the condition of the journal (L).
It must not be scratched or signs of splitting. Also
check the side (B).

- Let the pump continue to operate for another (30)
minutes after reaching the vacuum.

- Close the Manifold tap then switch off the vacuum
pump without disconnecting any exible hoses.

" If the outdoor temperature is between

+5 and +10 °C, use method 3 empty
(cf. APPENDIX 2).

- Remove the access plugs (A) from the valve controls.

" If an additional charge is requires, add the additional

charge before lling the hydraulic unit with gas.

Refer to paragraph Page22.

- First open the liquid valve (small) then the gas valve

(large) to maximum with an Allen key (anticlockwise
direction) without forcing it too far.

- Quickly disconnect the Manifold hose.

- Ret the 2 original plugs (ensure they are clean) and

tighten to the recommended torque from the table

gure 20, page 19. The sealing is performed in the

caps only metal to metal.

The outdoor unit does not contain any additional
refrigerating uid to allow the installation to be drained.

Drain by ushing is strictly forbidden.

2.8.2 Final leak test

The sealing test must be performed with a certied gas
detector (sensitivity 5g/year).

Once the refrigerating circuit has been lled with gas
as described previously, check all of the refrigerating
connectors of the installation for leaks (4 connectors).
If the tube expanders have been correctly used, there
should be no leaks. If required check the refrigerating
tap plugs for leaks.

" In case of leaks:

- Feed gas into the outdoor unit (pump down). The
pressure must not drop below atmospheric pressure
(0 bar relative read on Manifold) to avoid polluting the
gas collected with air or humidity.

- Make the connection again,

- Re-start the commissioning procedure.

none 250 g

The volumes on the outdoor units correspond to
maximum distances between the outdoor unit and
Hydraulic module dened in gure 21, page 20. If the
distances are greater, an additional volume of R410A
is required. The additional volume added depends, for
each type of appliance, on the distance between the

outdoor unit and the hydraulic module. The additional

volume added of R410A must only be added by a
qualied specialist.

• Example of additional volume added:

An outdoor unit at a distance of 17 m from the hydraulic
requires an additional charge of:

Additional volume = (17 – 15) x 50 = 100 g

The volume must be added after evacuation and
before connecting the gas to the Hydraulic module,
as follows:

- Disconnect the vacuum pump (yellow hose) and
connect in place a bottle place of R410A in the

position of liquid drawing.

- Open the tap of the bottle.

- Drain the yellow exible hose by loosening it slightly

on the manifold side.

- Place the bottle on precision scales with a minimum of
10g. Note the weight.

- Carefully open the blue tap slightly and monitor the
value displayed on the scales.

- As soon as the value displayed has dropped by the
value of the calculated additional charge, close the
bottle and disconnect it.

- Sharply disconnect the exible hose from the appliance.

- Add the gas to the hydraulic module.

" Warning!

• Only use R410A!

• Only use tools adapted to R410A (set of pressure
gauges).

• Always add charge in liquid phase.

• Do not exceed the maximum length or difference in height.

2.8.4 Collecting the refrigerating uid

in the outdoor unit

" Only for the 3 phase models

Carry out the following procedures to collect the
refrigerating uid.

1. Place the ON/OFF switch in the position 0 (item 27,

gure 9, page 10).

2. Remove the front panel of the hydraulic module.

4. The outdoor unit starts in the cold mode for
approximately 3 minutes after it is switched on.
Close the liquid valve on the outdoor unit 1 minute
after the outdoor unit is started.

5. Close the gas valve on the outdoor unit 1 to 2
minutes after closing the liquid valve, while the
outdoor unit continues to turn.

6. Disconnect the electrical power supply.

Remarks:

- Check that the ON/OFF switch is in the position 0
before pressing DIP SW1.

- When the heat pump is operating, the collection cannot
be activated even if the DIP SW 1 is at ON.

- Do not forget to place the DIP SW 1 to OFF once

2.9.1 General

The connection must comply with trade practices
according to the regulations in force.

The heating circulation pump is integrated into the

hydraulic module.
Connect the pipe of the central heating to the hydraulic

module respecting the direction of the circulation.
The diameter of the pipes, between the Hydraulic

module and the heating manifold must be at least equal
to 1 inch (26x34 mm).

Calculate the diameter of the pipes in function of the
ow rates and lengths of the hydraulic systems.

Tightening torque: 15 to 35 Nm.
Use union connectors to facilitate the removal of the

hydraulic module.

Prefer the use of exible connector hoses to avoid
transmitting noise and vibrations to the building.

Connect the evacuations of the drain tap and the safety
valve to the drain.

Verify the correct functioning of the expansion system.
Control the vessel pressure (precharge 1 bar) and the

safety valve setting.
Reminder: Make the assembly impervious respecting

trade practices in force for the plumbing work:

- Use suitable seals (bre seals, O rings).

- Use Teon or hemp tape.

- Use sealant (synthetic as required).

There is no need for glycol. If water containing glycol
is used, carry out an annual check of the quality of the

glycol. The use of glycol monoethylene is prohibited.

" In certain installations, the presence of different

metals may cause corrosion problems; in which
case the formation of metal particles and sludge
may be observed in the hydraulic circuit.

" In this case, it is preferable to use a corrosion

inhibitor in the proportions recommended by its
manufacturer.

" It is also necessary to ensure that the water

2.14 Verications and commissioning

• Carry out the usual verications on the burner and its
power supply circuit.

• Check the turbulators are tted correctly.

• Check correct assembly of electrical connections on
the terminals.Check draught.

• Connect the appliance to the mains supply and start
up:

- Engage the main isolator switch of the installation.
When rst commissioning (or in winter), to

preheat the compressor, engage the main circuit
breaker of the installation (outdoor unit power
supply) a few hours before carrying out the tests.

- Switch on the Start/Stop button of the heat pump.
To ensure the appliance operates correctly:

Check that the phase-neutral polarity of the
electrical power supply is respected.

When put into service and every time that the Start/Stop
switch is switched off and then back on, the outdoor
unit requires approximately 4 min. to start up even if the
regulation has demanded heating.

The display may show error 370 when starting.
This error code will disappear when the
communication between the refrigerating unit
and the hydraulic module is established (again).

During the initialisation phase of the regulator, all of
the symbols are displayed, then the "Data, update",
then"Heat pump status" is displayed.

3.3 Water logic

The operation of the heat pump is controlled by the
water logic.

The reference temperature of the heating circuit water
is adjusted in function of the outdoor temperature.

If there are thermostatic valves tted to the installation,
they must be opened fully or set higher than the normal
value of the ambient temperature.

3.3.1 Manual setting

During the installation, the water logic must be set in
function of the heating transmitters and the insulation
of the building.

The water law curves (gure 45) refer to an ambient
reference value equal to 20 °C.

The slope of the water law (parameter 720) determines
the impact of the outdoor temperature variations on the
initial heating temperature variations.

Specic case: When the slope is equal to or greater than
2 and the outdoor temperature is greater than 2 °C, it is
possible there is a little discomfort in the home. In this
case, it is possible to increase the value of parameter

3700.

The water law offset (parameter 721) modies the initial
temperature of all the curves, without modifying the
slope (gure 46) .

The corrective actions in case of discomfort are listed in
the table (gure 47).

7 Servicing of the installation

Before carrying out any work, ensure that the general
electrical power supply and the fuel supply valve are
switched off.

7.1 Checking the hydraulic circuit

" Warning:If frequent rells are required it is

essential that you look for any leaks.

If lling and re-pressurization are required,
check what type of uid has been used initially.

Recommended lling pressure: between 1 and 2 bar
(the precise lling pressure is determined according to
the manometric height of the installation).

Every year,

- Check the pressure of the expansion tank (pre-inate
to 1 bar) and the correct operation of the safety valve.

- Check the safety unit on the sanitary cold water inlet.
Make it work as prescribed by the manufacturer.

- Check the circuit breaker.

7.2 Servicing the tank

The tank must be serviced once a year (the frequency
may vary depending on the hardness of the water)

- Reduce the pressure in the primary circuit (P < 0.5
bar).

- Drain the tank by turning the security group valve

- Remove the inspection hatch.

- Remove any scale deposits that may have accumulated

in the tank. It is preferable to leave any limescale xed
to the walls of the tank: it forms a protective layer.

- Gently remove any limescale deposit on the
thermowell. Do not use any metal objects or chemical
or abrasive products.

- Replace the hatch gasket at each disassembly of the
hatch.

- Reinstall the inspection hatch and tighten the bolts

"crossover".

" Don’t forget to put the sensor into the sanitary

thermowell.

7.4 Checking the electrical circuit

- Check connections and possible tightening.

- Checking the condition of the cables and plates.

7.5 Servicing of the heat exchanger

The boiler must be serviced regularly to maintain high
its output.

Depending on the operating conditions, the servicing
operation is to be carried out once or twice a year.

- Switch off the electrical power supply to the appliance.

- Open the rebox door.

- Remove the turbulators and clean them.

- Clean the exchanger using a scraper and a nylon

swab Ø 50 mm.

- Remove residues of cleaning by the soot hatch.

- Don’t use abrasive material or metal brush on the

ceramic door protection

- Ret all of the parts correctly.

- Close the soot hatch and the rebox door, check for

leaks

" Lightly tighten the screws of the closing door

7.6 Servicing the burner

The burner must be serviced regularly (cell, jet,
combustion head, electrode, pump lter) by a specialist
once or twice a year depending on the conditions of use.

These servicing operations are detailed in the technical
instructions of the burner.

Before carrying out any work, ensure that the general
electrical power supply and the fuel supply valve are
switched off.

After retting, check the operation of the burner to
ensure that the setting has not been modied and that
they suit the desired power level if the boiler.

- The "sweeping" (gure 56) push button authorises the
burner operation for one hour.

- Create a heating demand to start the burner.

7.3 Checking the outdoor unit

- Dust off the heat exchanger if necessary, being careful
not to damage the ns.

- Straighten the vanes using a comb.

- Check that there is nothing obstructing the passage
of air.

- Check the fan.

- Verify that condensate drain is not obstructed.

• Checking the refrigerating circuit:

- When the volume of refrigerating uid is over 2 kg, the
refrigerating circuit must be checked every year by a
company that complies with the legal requirements in
force (cf. § 2.1, page 13)

- Check that there are no leaks (connectors, valves...).

- 62 -

7.6.1 Servicing the chimney

The chimney must be checked and cleaned and by a
specialist at least once a year.

7.6.2 Servicing the safety appliances

Every year, check that the expansion system is operating
correctly. Check the pressure of the expansion tank and
the calibration of the safety valve.

Check the safety unit on the domestic cold water inlet.
